MEANS FOR SECURING WINDOW SHADES TO METALLIC ROLLERS Filed Jan. 19, 1928 Patented Feb. 11, 1930 UNITED STATES PATENT OFFICE EDWARD BEUKAUF, JR., OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO CAREY- MGFALL ('10., OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF PENNSYL- VAN IA MEANS FOR SECURING WINDOW SHADES TO METALLIC ROLLERS Application filed January 19, 1928. Serial No. 247,863.

This invention relates to Window shades having metal rollers. The principal object of the invention is to provide means for securing the shade material to the roller, whlch will permit the shade material to be quickly applied to the roller.

Referring to the accompanying drawings:

Fig. 1 is a sectional perspective view of a metal shade roller made in accordance with my invention;

Fig. 2 is a view similar to Fig. 1, showing the shade material applied to the roller;

Fig. 3 is a transverse sectional elevation taken on the line 33, Fig. 2; and

Fig. 4 is a view similar to Fig. 3, showing the shade material in the course of being applied to the roller.

The shade roller comprises a hollow metal barrel or cylinder 1, which may or may not be provided with a head or flange 2 at either end as desired. The roller is provided with the usual trunnions, spring and locking mechanism for permitting the shade to be raised and lowered in the usual manner.

In the barrel 1 and spaced longitudinally thereof is formed a series of apertures 3, 3. Extending into each of these apertures from one side thereof is a tongue 4. These tongues 4 are formed integral with and of the material of which the barrel is composed and are in alignment with each other, longitudinally of the said barrel. Each tongue 4, in the present instance, is provided with an arrow head 5, having shoulders or barbs 6, 6 formed thereon which act to prevent the shade material from being too easily detached from the tongues 4.

In applying the shade material 00 to the roller, the tongues 4, 4 are bent outwardly, as illustrated in Fig. 4, after which the shade material a: is forced onto the pointed arrow heads 5 of the tongues and past the barbs or shoulders 6, 6 of each arrow head, which prevents the shade material from accidently slipping off or being too easily removed from the said arrow heads, after which the tongues 4 are pressed back into the apertures 3 of the roller carrying the surrounding portions of y the shade material into the respective open- 50 ings 3 as illustrated in Figs. 2 and 3, thereby efliciently securing the shade material to the roller.

Obviously the tongues 4 may be provided with any desirable form of barb to prevent the easy removal of the shade material from the tongue, in place of the arrow heads which are illustrated in the drawings.

The invention is especially adaptable to the window shades or curtains used in automobiles of the various closed types and in which the shade material is usually soft and extremely pliable.

The tongues 4 could, if desired, be formed separately and rigidly attached to the roller in any suitable manner, without departing from the essential features of the invention.

The tongues 4, by reason of their occupying positions substantially within the peripheral limits of the roller, prevent projecting humps from being formed at the places of attachment which would interfere with the proper rolling of the shade material on the roller.

I claim:

1. A window shade roller provided with a tongue rigidly attached at one end to the roller and having a free end adapted to pierce the shade material being applied to the roller and a barb on said tongue adapted to engage said shade material and prevent the said shade material from being easily-detached from said tongue.

2. A window shade roller provided with a series of tongues rigidly attached to said roller in alignment longitudinally of said roller, each tongue having a free end extending circumferentially of said roller and adapted to pierce the shade material being applied to the roller; and a barb on each tongue adapted to engage said shade material and prevent the said shade material from being readily detached from said tongue.

3. A cylindrical window shade roller having a series of openings formed in its periphcry; a series of tongues rigidly attached to said roller and each having a free end extending into the respective openings in said roller and adapted to pierce the material of which the shade is formed; and a barb on the said tree portion of each tongue adapted to engage said shade material and prevent its being readily detached from said tongue.

4. A cylindrical window shade roller having a series of openings formed in its periphery; a series of tongues rigidly attached to said roller, each tongue having a free end adapted to pierce the shade material and to extend into one of said openings of the roller and adapted to occupy a position'suhstantially Within the limits defined by the periphery of said roller; and a barb on each tongue adapted to engage the shade material and prevent its being readily detached from said tongue.

5. A cylindrical window shade roller; a series of tongues on said roller each having a free end adapted to pierce the material of which the window shade is formed, said tongues being adapted to occupy positions substantially within limits defined by the periphery of the roller, the said roller being so constructed as to form a clearance around the free end of each tongue to permit the shade material to be held by said tongue below the peripheral surface of the roller.

6. A hollow cylindrical roller having a plurality of openings formed in the wall thereof; a plurality of tongues formed integral with said wall and extending respectively into said openings, said tongues lying substantially within the peripheral limits of said roller; and a barb formed on each of said tongues.

7. A hollow cylindrical roller having a plurality of openings formed in the wall thereof; a plurality of tongues formed integral with said wall and extending respectively into said openings, said tongues lying substantially within the peripheral limits of said roller; and barbs formed on the free end of and extending laterally from each of said tongues.

8. A hollow cylindrical roller having a plurality of openings formed in the Wall thereof and spaced longitudinally of said roller on a line substantially parallel to the axis of said roller; a plurality of tongues formed integral with the said roller wall and extending into the plurality of openings respectively and a pointed arrow head formed on each tongue for piercing the material of which thewindow shade is formed, securing said material to the roller, and preventing its being readily detached from the roller.

9. A hollow cylindrical roller having a plurality of openings formed in the wall thereof and spaced longitudinally of said roller on a line substantially parallel to the axis of said roller; a plurality of tongues formed integral with the said roller wall and extending into the plurality of openings respectively and a pointed arrow head formed on each tongue for piercing the material of which the window shade is formed, securing said material to the roller, and preventing its being readily detached from the roller, said tongues and arrow heads and the portions of the shade material engaged thereby lying substantially within the peripheral limits of the said roller.

10. A hollow cylindrical roller having a plurality of openings formed in the wall thereof and spaced longitudinally of said roller on a line substantially parallel to the axis of said roller; a plurality of tongues formed integral with the said roller wall and extending circumferentially ofsaid roller into the plurality of openings -respectively and a pointed arrow head formed on each tongue for piercing the material of which the window shade is formed, securing said material to the roller, and preventing its being readily detached from the roller.
